"Qt has reached another important evolutionary milestone today. We are very proud to announce that Qt 4.8.0 has now been released. Many people have worked long and hard to deliver Qt 4.8.0. Today that hard work reaches final release maturity, and we are celebrating! Featuring Qt Platform Abstraction, threaded OpenGL support, multithreaded HTTP and optimized file system access, Qt 4.8.0 can be downloaded as binary or source packages."

Thanks for the info. Even though I am kind of satisfied with the level of features/stability LibreOffice reached, I keep checking Calligra because of its potential speed/integration inside KDE. May give it a try when openSUSE 12.1 stabilize enough to trigger my upgrade cycle.
